NR4A1 and atherosclerosis: In this study, we first identified DE circRNAs and circRNA-miRNA-mRNA networks associated with angiogenesis in atherosclerosis, after which we verified a novel circSCRG1 and provided evidence, for the first time, that the circSCRG1/miR-1268b/NR4A1 axis regulates ox-LDL-induced angiogenesis in vitro.
